FLUSHING APPARATUS FOR WATERr-CLOSETS.

To all whom it may concern Be it known that I, FRANCIS M. MAoKIN, acitizen of the United States, residing at Baltimore, in the State ofMaryland, have invented certain new and useful Improvements in FlushingApparatus for WVater- Closets, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention has relation to flushing apparatus for water-closets ofthat class wherein, upon the lowering of the water-closet seat, a valve,preferably located underground below the frost line, is opened andpermits water to flow through a supply pipe to a closed tank and, whenthe seat is allowed to rise, the supply valve will close automaticallyand a second valve will be opened to permit the water from the tank toflow into and flush the closet bowl.

The object of my invention is to produce a flushing apparatus of theabove character which will be of comparatively cheap and simpleconstruction, containing as few parts as possible, not liable todisarrangement while in use and easily adjusted and repaired in case ofnecessity.

My invention consists in the novel construction and combination of partshereinafter described and claimed.

I have illustrated my invention in the ac companying drawing wherein:

Figure l is a side elevation of a complete apparatus including awater-closet and a flushing tank having my improvements applied. Fig. 2is a vertical sectional view of the flushing apparatus and a portion ofthe water-closet and seat shown in Fig. 1. Fig. 3 is a rear elevation ofthe parts shown in Fig. 1.

My invention is applied to water-closet bowls of any of the usualconstructions and I have shown it as applied to an ordinary hoppercloset, 1, which is formed with rearwardly projecting lugs 2, piercedfor the reception of bolts 3, that pass through the lugs 2, and aresecured in position by nuts 4, the bolts 3, being formed with eyes 5, ontheir upper ends to receive the pintle 6, of the seat hinge 7. The hinge7 is rigidly secured to the seat 8 and is formed with upwardly angledand rearwardly projecting arms 9, terminating in rounded ends 10.Between the arms 9, is arranged a crosshead 11 which is formed withcurved lugs 12, extending outwardly over the upper Specification ofLetters Patent.

rounded ends 10 of the arms 9, the crosshead being thus supported on thearms, but without other connections between them so that the cross-headmay be moved upwardly and allowed to descend vertically when the armsare swung on the pintle 6 by the lowering and raising of the seat.

The closet bowl 1, is formed with a spud 13, in which is secured thecoupling member 14, that is connected by a nut 15, to the horizontalbranch 16, of a valve casing 17. The valve casing 17, has a horizontalbranch 18, diametrically opposite the branch 16 and the branch 18 isconnected by an elbow coupling l9, and a vertical pipe 20 with a closedflush tank 21.

Vithin the branch 16 is arranged a hori Zontally pivoted flap valve 22,that seats against the beveled edge of a passage 23, formed in avertical partition 24, that intervenes betweenthe main casing 17, andthe branch 16. The flap valve 22, is provided with a lug 25, that isdownwardly beveled on its lower side, from its base to approximately itsouter end, as shown at 26, and this lug is engaged by a laterallyextending tooth 27, carried by a collar 28, formed on the verticallymovable valve stem 29. The valve casing 17 is provided with a screw capor top 30 having a stufling box of the usual form and the stem 29,extends through this stufling box and is threaded at its upper end andscrews through the cross-head 11. A vertical spring 31, is arrangedbetween the collar 28, on the valve stem 29, and the cap or top 30 andthis spring serves, when the seat 8 is relieved from pressure, to raisethe seat and at the same time to force the valve stem 29 downwardly.

The main valve casing 17, is connected by a section of pipe 32, with asupplementary valve casing 33, that is preferably arranged in the groundbelow the frost line, when the closet is located out of doors, beingusually located at about the level of the soil pipe trap and saidsupplementary valve casing is provided with a waste branch 34, that.

communicates with the soil pipe by a pipe 35.

Within the supplementary casing 33, is located the vertically movablevalve 36, which is carried on the lower end of valve stem 29, and, whenat its lowermost position, seats at 37 and closes the inlet passage 38,which is connected to the water supply pipe, (not shown). The upperportion 39 of the valve 36 is cylindrical in form and fits snugly in thecentral cylindrical portion of the valve casing 33, and when the valveis in the elevated position shown, tightly closes the waste passage inbranch 34.

The supplementary valve casing 33, is formed with a curved passage 40,which extends as shown from a point just above the valve seat 37, to apoint above the position occupied by the upper portion 39, of the valve36, so that when the valve is in the elevated position shown in thedrawing, there will be free passage for water coming in through inletpassage 38, around the valve 36.

Operation: The parts being in the position shown in the drawing, withthe closet seat held down, the water from the source of supply flowsthrough inlet passage 38, and thence through passage 40, pipe 32, mainvalve casing 17, elbow coupling 19, and pipe 20, to the tank 21, whichbecomes filled with water which is retained therein, so long as thecloset seat is held down. Upon releasing the closet seat the spring 31,raises the seat and forces down the valve stem 29, and causes the valve36 to seat at 3'7, and close the inlet 38, and at the same time opensthe waste passage to the soil pipe through branch 34. The descent of thevalve stem releases the lug 2 from engagement with the tooth 27,whereupon the flap valve 22, swings back from its seat and the waterflows through the branch 19, into the closet bowl until the tank 21 isemptied. After the tank has been emptied, the water which remains in thelower part of the main valve casing and the pipe 32, drains off slowlythrough the waste passage in branch 34, to the soil pipe. As soon thebowl has been flushed and the flow of water from the tank ceases, thevalve 522, swings down against its seat 23, and thereafter, when thecloset seat is depressed, and the valve stem 29 is drawn up by theupward pressure of the arms 9, on the cross-head 11, the tooth 27,engages the lug 25, and pulls the valve tightly against its seat andholds it there until it is again released by the raising of the lid. Theupward movement of the valve stem 29, raises the valve 36, from itsseat, thereby allowing the water to again flow into the tank and at thesame time closing the waste passage through branch 34, to the soil pipe.

I claim:

1. In water-closet flushing apparatus, the combination of a main valvecasing, a flap valve adapted to close the outlet of said main valvecasing, a supplementary valve casing, a valve in said supplementaryvalve casing adapted to control the inlet passage thereof, a valve stemcarrying the last named valve, means carried by said valve stem forholding the flap valve in closed position when the valve in thesupplementary valve casing is in open position.
